Grant permission on SCOTT/tiger schema

grant select, insert, update, delete on EM to BOMBAC
I want to add permission that user BOMBAC can see EM table from SCOTT/tiger scheme and use it. But he can not see and use it. Any idea why?
regards

yes i try with public but it seems that i do not have enought privilegies
*Cause: An attempt was made to change the current username or password
without the appropriate privilege. This error also occurs if
attempting to install a database without the necessary operating
system privileges.
When Trusted Oracle is configure in DBMS MAC, this error may occur
if the user was granted the necessary privilege at a higher label
than the current login.
*Action: Ask the database administrator to perform the operation or grant
the required privileges.
For Trusted Oracle users getting this error although granted the
the appropriate privilege at a higher label, ask the database
administrator to regrant the privilege at the appropriate label.

How to test basic sql queries online(for Sql Server 2012 and up versions) ?

Oracle 11g SQL signon - The scott/tiger routine...

I just installed Oracle 11g.
First, what is the ID/PW into SQL - it used to be scott/tiger. I changed it to what I wanted on install. However, when I logon and type scott then tiger its says
account locked out. I tried scott and my own "created pw". It still didn't let me in. Is there an "easy" fix?
I have to get this aspect going to get to first base. How do I get around this or FIX it????

By default, most of the demo accounts are created but locked so that they are not security holes if they are inadvertently included in a production install. To unlock scott
- Connect as SYS, i.e. from the command line (DOS prompt in Windows)
sqlplus / as sysdba- Unlock the account
SQL> ALTER USER scott ACCOUNT UNLOCK;Now, you should be able to log in as SCOTT. If you want to log in as HR, OE, or any of the other demo accounts, you'd repeat the procedure.

Sql queries for this database schema

1) Patient—PatientID, Name, DOB
2) Doctor—DoctorID, Name, MedLicenseNumber, Phone
3) Medication—MedicationID, BrandName, GenericName
4) Prescription—PrescriptionID, Date, PatientID, PrescriberID, MedicationID
Specify the SQL queries to retrieve:
a) The prescription information along with patient name, DOB, medication brand name, and prescribing doctor name sorted by most recent date.
b) The most prescribed generic medication name

Looks like assignment question to me
a, seems to be a case of straight forward join among all the involved tables on common fields. Suggest you learn about joins and try it out yourself.
see below link
http://www.w3schools.com/sql/sql_join.asp
b, Have a look at GROUP BY. you need to apply group by and take medicine name which repeats maximum (ie largest count value)

Try this (untested)
select ename, ename, emp.deptno, sal,
RATIO_TO_REPORT(sal) OVER ()*100 cmp_sal_pct,
RATIO_TO_REPORT(sal) OVER (PARTITION BY dept)*100 dept_sal_pct
from empRATIO_TO_REPORT is the key. If this doesn't work then check the docs.

Simple scott/tiger query in horizontal format

Hi Guys, this is my first thread to this forum, as I m a java developer and does not come across sql frequently.
I have a simple requirement.
I ll need this example to let u know, what is all I need.
You must be very well aware of the famous scott/tiger schema in Oracle database where the emp table has a many-one relationship with dept table.
Is there any way, where I can get the data in the below format (assuming one dept will have maximum 4 employees and minimum 0 employees)
DeptNo Employee1 Employee2 Employee3 Employee4
Accounting CLARK KING MILLER Null
Research JONES SCOTT ADAMS FORD
Sales ALLEN WARD NULL NULL
thanks in advance,
Abzee

Hi, Abzee,
Welcome to the forum!
That's called a Pivot and here's one way to do it:
WITH     got_rnum     AS
     SELECT     deptno
     ,     ename
     ,     ROW_NUMBER () OVER ( PARTITION BY deptno
                         ORDER BY        ename
                       )     AS rnum
     FROM     scott.emp
SELECT       d.dname
,       MIN (CASE WHEN r.rnum = 1 THEN r.ename END)     AS employee1
,       MIN (CASE WHEN r.rnum = 2 THEN r.ename END)     AS employee2
,       MIN (CASE WHEN r.rnum = 3 THEN r.ename END)     AS employee3
,       MIN (CASE WHEN r.rnum = 4 THEN r.ename END)     AS employee4
FROM       scott.dept     d
JOIN       got_rnum     r     ON     r.deptno     = d.deptno
GROUP BY d.dname
;To do a pivot, you must have columns or expressions that tell what row and column of the output correspond to each row of the input.
In this example, d.dname uniquely identifies the row of the output, but there's nothing that says that 'JONES' belongs in the employee1 column rather than the employee2 column. I used ROW_NUMBER to assign each employee a number, starting with 1 in each deptartment, for just that reason. I used ORDER BY ename, so that the employees will appear in alphabetic order. You could use any other way of sorting them (e.g., by salary or descending hiredate).
This site normally compresses multiple spaces into one space.

Connect string for scott/tiger

i've personal oracle 8i with only scott/tiger schema on my pc. i installed forms 6i. when i try to connect to my scott/tiger schema it gives me tns listener error. i'm using scott/tiger as username/password. i tried keeping Host string null and 'ORCL' but no luck....
any help is appreciated
thank you very much
---himanshu

Himanshu,
When u have the default database and Oracle Forms on the same machine, from SQL prompt it will connect to the database without any connect string. But when u connect from Forms u NEED to have a TNS entry. Open explorer --> Oracle Home directory --> Network --> Admin and u will find the Tnsnames.ora Open this file and create a new TNS entry ( u will find examples ) Give ur machine IP address/or user name and SID ( which will be ORCL by default ) save this file. Then connect from Forms it will connect. Good luck
orcl.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = your machine IP)
(Port = 1521)
(CONNECT_DATA = (SID = ORCL)
now orcl is ur TNS name

Trouble logging into sql using scott/tiger..please help..URGENT!!!

hai friends!
I installed D2K recently. Iam unable to login to sql (directly or from D2K forms) using the usual username/password..scott/tiger,system/manager,demo/demo. I get the following error message :
TNS error: Unable to connect to destination
Please help me out!
thanX,
raji

what is your error number.
Did you try to look up this number in the oracle error book?
Usually you can also find the solution there.
My bet is that your tnsnames.ora file is not set properly.

Sql plus not accepting user id and password as scott, tiger resp

Hi, this is mihir shah
I have just installed oracle9i
And I have a problem in opening the sql plus. It asks for user id and pass but when entered scott, tiger it always gives a tns error.
Could you tell me how to make a database & how to log on & how to make a new user id and password

It seem that you have problem with network connectivity to you database.
Check the listener status and the configuration of the files: tnsnames.ora & listener.ora
In all cases you must specified the error.

Aborting Sql Queries

hello all
i have a query. i want to abort a query running in a thread with a help of another thread
my programs looks like this
public class test
          public static void main(String args[]) throws Exception
               String driverName = "oracle.jdbc.driver.OracleDriver";
               String url = "jdbc:oracle:thin:@192.168.103.46:1521:test";
          Class.forName(driverName); // load the driver
               Connection connection = DriverManager.getConnection(url, "scott", "tiger");
               ConnThread connThread = new ConnThread();
               connThread.stmt = connection.prepareCall("{call NEWOBJECT(?)}");
connThread.stmt.registerOutParameter(1,OracleTypes.CURSOR);
               connThread.start();
               System.out.println ("waiting");
               Thread.sleep(20);
               System.out.println ("waiting done");
               System.out.println ("closing conn");
               connThread.stmt.cancel();
               System.out.println ("closing conn done");
     class ConnThread extends Thread
          CallableStatement stmt = null;
          public void run()

                    stmt.executeQuery();
                    System.out.println ("Executing query done");
               catch(Exception e)
                    e.printStackTrace();

Need help in SQL Queries using GUI controls or variables

Hello, all
I have a big problem (I have already had with Visual Basic a few mounths ago) with Java while writing my SQL Queries.
I would like to know how I must do to use variable data or GUI control data in my SQL Query to select only some records.
Here, my first Query that works without any problem (no WHERE clause !!!) :
Statement requeteBedes = connectBedes.createStatement();
ResultSet resultatSeries = requeteBedes.executeQuery("SELECT * FROM Series");
initComboBoxSeries(resultatSeries);the method "initComboBoxSeries" fills a JComboBox with all the names of the series in my database.
Here comes my problem.I would like to use the value of the selected "series" in the JComboBox to search in another table of the same Database. I made another statement but it returns a Null ResultSet :
ResultSet resultatSearchAlbumsFromSeries = requeteBedes.executeQuery("SELECT * FROM bandes_dess WHERE ser_nom = '" + strComboBoxSeriesSelected + "' "); The variable strComboBoxSeriesSelected contains the value of the selected line in the combobox with all the series, filled after the first query that is here above and that works very well.
Could some one help me and tell me how I must use variables or GUI controls values in my SQL Queries or tell me if there is a place where I could find an explanation of that kind of problems (like more "advanced SQL Queries", as the ones currently used in all the Learning Java 2 books)
Thank you all for your help.
Christian.

executeQuery() will never return null. At least that's what the spec says. You are probably catching an exception (probably a syntax error caused by a single quote in strComboBoxSeriesSelected) and ignoring it. Or do you mean the ResultSet contains no rows?
Anyway, to use parameterized queries, take a look at PreparedStatements. Your code should look like this using PreparedStatement:Statement requeteBedes = connectBedes.prepareStatement("SELECT * FROM bandes_dess WHERE ser_nom = ?");
requeteBedes.setString(1, strComboBoxSeriesSelected);
ResultSet resultatSeries = requeteBedes.executeQuery();Alin.
